I added commands to shape the conversation: (#218)

* I added commands to shape the conversation:

`/rethink <text>` will change the internal dialog of the last assistant message.
`/rewrite <text>` will change the last answer of the assistant.

Both commands can be used to change how the conversation continues in
some pretty drastic and powerfull ways.

* remove magic numbers

* add disclaimer
